Why does my cat open their mouth and look around?
You may have found your cat walking around the house and all of a sudden they stop and open their mouth wide as they look around the room. It can be a bit alarming but the explanation behind this behavior it pretty cool. Cats do this as a way to smell and determine the origin of an interesting scent. Located in the roof of their mouth, behind their front teeth, is the Jacobson’s organ. Other big cats as well as horses and snakes have the same receptor. So when they are sniffing the air and open their mouth, they are using this receptor to draw the scent in and focus it on the Jacobson’s organ in order to find out where the scent came from and what caused it.
